Ran into a Warren fan powered box, yesterday. It had an ECM fan with an Evolution ECM contoller on it. It was showing all dashes on the display and no fan. Powered down to check out. Everything looked good and powered back up. Display showing rpm now, but also a F14.

I can't find any info on the controller. Still waiting for a call back from Warren Technologies. The model number is a FBIEA6100101FVSXFJQSBF6.

Looking for any info or experience with these?
